NPC - Non-positive curvature group actions and cohomology

In the 1990's Bestvina and Brady constructed groups that are FP but not finitely presented as the kernels of maps from right-angled Artin groups to Z.  I generalize this construction using branched coverings.  The main application is an uncountable family of groups of type FP.   A corollary is that every countable group embeds in a group of type FP_2.  I will explain the construction, and if time permits I will discuss the corollary and work with Ignat Soroko and Robert Kropholler on the quasi-isometry classification of the new groups.
